Abstract

The level structure of the N=81 nucleus¹⁴⁷Dy has been studied by γ-ray spectroscopy following reactions of 230-250 MeV^58,60Ni beams on⁸⁹Y and^90,92Zr targets. Yrast and near-yrast levels in¹⁴⁷Dy above the known 59-s 11/2^- state are established up to ∼3.7 MeV; they include isomeric levels at 2,681, 3,407 and 3,650 keV. Guided by the results of shell model calculations, we interpret most of the observed level as senioritythree states arising from the coupling of s_1/2, d_3/2, and h_11/2 neutron holes with πh_11/2².
